◆ SDL_PROPERTY_GLOBAL_VIDEO_WAYLAND_WL_DISPLAY_POINTER

#define SDL_PROPERTY_GLOBAL_VIDEO_WAYLAND_WL_DISPLAY_POINTER   "video.wayland.wl_display"

Global video properties

  • SDL_PROPERTY_GLOBAL_VIDEO_WAYLAND_WL_DISPLAY_POINTER: the pointer to the global wl_display object used by the Wayland video backend. Can be set before the video subsystem is initialized to import an external wl_display object from an application or toolkit for use in SDL, or read after initialization to export the wl_display used by the Wayland video backend. Setting this property after the video subsystem has been initialized has no effect, and reading it when the video subsystem is uninitialized will either return the user provided value, if one was set prior to initialization, or NULL. See docs/README-wayland.md for more information.

2214 * function pointers to OpenGL extensions.
2215 *
2216 * There are some quirks to looking up OpenGL functions that require some
2217 * extra care from the application. If you code carefully, you can handle
2218 * these quirks without any platform-specific code, though:
2219 *
2220 * - On Windows, function pointers are specific to the current GL context;
2221 * this means you need to have created a GL context and made it current
2222 * before calling SDL_GL_GetProcAddress(). If you recreate your context or
2223 * create a second context, you should assume that any existing function
2224 * pointers aren't valid to use with it. This is (currently) a
2225 * Windows-specific limitation, and in practice lots of drivers don't suffer
2226 * this limitation, but it is still the way the wgl API is documented to
2227 * work and you should expect crashes if you don't respect it. Store a copy
2228 * of the function pointers that comes and goes with context lifespan.
2229 * - On X11, function pointers returned by this function are valid for any
2230 * context, and can even be looked up before a context is created at all.
2231 * This means that, for at least some common OpenGL implementations, if you
2232 * look up a function that doesn't exist, you'll get a non-NULL result that
2233 * is _NOT_ safe to call. You must always make sure the function is actually
2234 * available for a given GL context before calling it, by checking for the
2235 * existence of the appropriate extension with SDL_GL_ExtensionSupported(),
2236 * or verifying that the version of OpenGL you're using offers the function
2237 * as core functionality.
2238 * - Some OpenGL drivers, on all platforms, *will* return NULL if a function
2239 * isn't supported, but you can't count on this behavior. Check for
2240 * extensions you use, and if you get a NULL anyway, act as if that
2241 * extension wasn't available. This is probably a bug in the driver, but you
2242 * can code defensively for this scenario anyhow.
2243 * - Just because you're on Linux/Unix, don't assume you'll be using X11.
2244 * Next-gen display servers are waiting to replace it, and may or may not
2245 * make the same promises about function pointers.
2246 * - OpenGL function pointers must be declared `APIENTRY` as in the example
2247 * code. This will ensure the proper calling convention is followed on
2248 * platforms where this matters (Win32) thereby avoiding stack corruption.

Function Documentation

◆ SDL_CreatePopupWindow()

SDL_Window * SDL_CreatePopupWindow ( SDL_Window parent,
int  offset_x,
int  offset_y,
int  w,
int  h,
Uint32  flags 
)
extern

Create a child popup window of the specified parent window.

'flags' must contain exactly one of the following: - 'SDL_WINDOW_TOOLTIP': The popup window is a tooltip and will not pass any input events. - 'SDL_WINDOW_POPUP_MENU': The popup window is a popup menu. The topmost popup menu will implicitly gain the keyboard focus.

The following flags are not relevant to popup window creation and will be ignored:

  • 'SDL_WINDOW_MINIMIZED'
  • 'SDL_WINDOW_MAXIMIZED'
  • 'SDL_WINDOW_FULLSCREEN'
  • 'SDL_WINDOW_BORDERLESS'

The parent parameter must be non-null and a valid window. The parent of a popup window can be either a regular, toplevel window, or another popup window.

Popup windows cannot be minimized, maximized, made fullscreen, raised, flash, be made a modal window, be the parent of a modal window, or grab the mouse and/or keyboard. Attempts to do so will fail.

Popup windows implicitly do not have a border/decorations and do not appear on the taskbar/dock or in lists of windows such as alt-tab menus.

If a parent window is hidden, any child popup windows will be recursively hidden as well. Child popup windows not explicitly hidden will be restored when the parent is shown.

If the parent window is destroyed, any child popup windows will be recursively destroyed as well.

Parameters
parentthe parent of the window, must not be NULL
offset_xthe x position of the popup window relative to the origin of the parent
offset_ythe y position of the popup window relative to the origin of the parent window
wthe width of the window
hthe height of the window
flagsSDL_WINDOW_TOOLTIP or SDL_WINDOW_POPUP MENU, and zero or more additional SDL_WindowFlags OR'd together.
Returns
the window that was created or NULL on failure; call SDL_GetError() for more information.
Since
This function is available since SDL 3.0.0.

◆ SDL_CreateWindow()

SDL_Window * SDL_CreateWindow ( const char *  title,
int  w,
int  h,
Uint32  flags 
)
extern

Create a window with the specified dimensions and flags.

flags may be any of the following OR'd together:

  • SDL_WINDOW_FULLSCREEN: fullscreen window at desktop resolution
  • SDL_WINDOW_OPENGL: window usable with an OpenGL context
  • SDL_WINDOW_VULKAN: window usable with a Vulkan instance
  • SDL_WINDOW_METAL: window usable with a Metal instance
  • SDL_WINDOW_HIDDEN: window is not visible
  • SDL_WINDOW_BORDERLESS: no window decoration
  • SDL_WINDOW_RESIZABLE: window can be resized
  • SDL_WINDOW_MINIMIZED: window is minimized
  • SDL_WINDOW_MAXIMIZED: window is maximized
  • SDL_WINDOW_MOUSE_GRABBED: window has grabbed mouse focus

The SDL_Window is implicitly shown if SDL_WINDOW_HIDDEN is not set.

On Apple's macOS, you must set the NSHighResolutionCapable Info.plist property to YES, otherwise you will not receive a High-DPI OpenGL canvas.

The window pixel size may differ from its window coordinate size if the window is on a high pixel density display. Use SDL_GetWindowSize() to query the client area's size in window coordinates, and SDL_GetWindowSizeInPixels() or SDL_GetRenderOutputSize() to query the drawable size in pixels. Note that the drawable size can vary after the window is created and should be queried again if you get an SDL_EVENT_WINDOW_PIXEL_SIZE_CHANGED event.

If the window is created with any of the SDL_WINDOW_OPENGL or SDL_WINDOW_VULKAN flags, then the corresponding LoadLibrary function (SDL_GL_LoadLibrary or SDL_Vulkan_LoadLibrary) is called and the corresponding UnloadLibrary function is called by SDL_DestroyWindow().

If SDL_WINDOW_VULKAN is specified and there isn't a working Vulkan driver, SDL_CreateWindow() will fail because SDL_Vulkan_LoadLibrary() will fail.

If SDL_WINDOW_METAL is specified on an OS that does not support Metal, SDL_CreateWindow() will fail.

On non-Apple devices, SDL requires you to either not link to the Vulkan loader or link to a dynamic library version. This limitation may be removed in a future version of SDL.

Parameters
titlethe title of the window, in UTF-8 encoding
wthe width of the window
hthe height of the window
flags0, or one or more SDL_WindowFlags OR'd together
Returns
the window that was created or NULL on failure; call SDL_GetError() for more information.
Since
This function is available since SDL 3.0.0.

◆ SDL_CreateWindowWithProperties()

SDL_Window * SDL_CreateWindowWithProperties ( SDL_PropertiesID  props)
extern

Create a window with the specified properties.

These are the supported properties:

  • SDL_PROPERTY_WINDOW_CREATE_ALWAYS_ON_TOP_BOOLEAN: true if the window should be always on top
  • SDL_PROPERTY_WINDOW_CREATE_BORDERLESS_BOOLEAN: true if the window has no window decoration
  • SDL_PROPERTY_WINDOW_CREATE_FOCUSABLE_BOOLEAN: true if the window should accept keyboard input (defaults true)
  • SDL_PROPERTY_WINDOW_CREATE_FULLSCREEN_BOOLEAN: true if the window should start in fullscreen mode at desktop resolution
  • SDL_PROPERTY_WINDOW_CREATE_HEIGHT_NUMBER: the height of the window
  • SDL_PROPERTY_WINDOW_CREATE_HIDDEN_BOOLEAN: true if the window should start hidden
  • SDL_PROPERTY_WINDOW_CREATE_HIGH_PIXEL_DENSITY_BOOLEAN: true if the window uses a high pixel density buffer if possible
  • SDL_PROPERTY_WINDOW_CREATE_MAXIMIZED_BOOLEAN: true if the window should start maximized
  • SDL_PROPERTY_WINDOW_CREATE_MENU_BOOLEAN: true if the window is a popup menu
  • SDL_PROPERTY_WINDOW_CREATE_METAL_BOOLEAN: true if the window will be used with Metal rendering
  • SDL_PROPERTY_WINDOW_CREATE_MINIMIZED_BOOLEAN: true if the window should start minimized
  • SDL_PROPERTY_WINDOW_CREATE_MOUSE_GRABBED_BOOLEAN: true if the window starts with grabbed mouse focus
  • SDL_PROPERTY_WINDOW_CREATE_OPENGL_BOOLEAN: true if the window will be used with OpenGL rendering
  • SDL_PROPERTY_WINDOW_CREATE_PARENT_POINTER: an SDL_Window that will be the parent of this window, required for windows with the "toolip" and "menu" properties
  • SDL_PROPERTY_WINDOW_CREATE_RESIZABLE_BOOLEAN: true if the window should be resizable
  • SDL_PROPERTY_WINDOW_CREATE_TITLE_STRING: the title of the window, in UTF-8 encoding
  • SDL_PROPERTY_WINDOW_CREATE_TRANSPARENT_BOOLEAN: true if the window show transparent in the areas with alpha of 0
  • SDL_PROPERTY_WINDOW_CREATE_TOOLTIP_BOOLEAN: true if the window is a tooltip
  • SDL_PROPERTY_WINDOW_CREATE_UTILITY_BOOLEAN: true if the window is a utility window, not showing in the task bar and window list
  • SDL_PROPERTY_WINDOW_CREATE_VULKAN_BOOLEAN: true if the window will be used with Vulkan rendering
  • SDL_PROPERTY_WINDOW_CREATE_WIDTH_NUMBER: the width of the window
  • SDL_PROPERTY_WINDOW_CREATE_X_NUMBER: the x position of the window, or SDL_WINDOWPOS_CENTERED, defaults to SDL_WINDOWPOS_UNDEFINED. This is relative to the parent for windows with the "parent" property set.
  • SDL_PROPERTY_WINDOW_CREATE_Y_NUMBER: the y position of the window, or SDL_WINDOWPOS_CENTERED, defaults to SDL_WINDOWPOS_UNDEFINED. This is relative to the parent for windows with the "parent" property set.

These are additional supported properties on macOS:

  • SDL_PROPERTY_WINDOW_CREATE_COCOA_WINDOW_POINTER: the (__unsafe_unretained) NSWindow associated with the window, if you want to wrap an existing window.
  • SDL_PROPERTY_WINDOW_CREATE_COCOA_VIEW_POINTER: the (__unsafe_unretained) NSView associated with the window, defaults to [window contentView]

These are additional supported properties on Wayland:

  • SDL_PROPERTY_WINDOW_CREATE_WAYLAND_SURFACE_ROLE_CUSTOM_BOOLEAN - true if the application wants to use the Wayland surface for a custom role and does not want it attached to an XDG toplevel window. See docs/README-wayland.md for more information on using custom surfaces.
  • SDL_PROPERTY_WINDOW_CREATE_WAYLAND_CREATE_EGL_WINDOW_BOOLEAN - true if the application wants an associatedwl_egl_windowobject to be created, even if the window does not have the OpenGL property or flag set. -SDL_PROPERTY_WINDOW_CREATE_WAYLAND_WL_SURFACE_POINTER` - the wl_surface associated with the window, if you want to wrap an existing window. See docs/README-wayland.md for more information.

These are additional supported properties on Windows:

  • SDL_PROPERTY_WINDOW_CREATE_WIN32_HWND_POINTER: the HWND associated with the window, if you want to wrap an existing window.
  • SDL_PROPERTY_WINDOW_CREATE_WIN32_PIXEL_FORMAT_HWND_POINTER: optional, another window to share pixel format with, useful for OpenGL windows

These are additional supported properties with X11:

  • SDL_PROPERTY_WINDOW_CREATE_X11_WINDOW_NUMBER: the X11 Window associated with the window, if you want to wrap an existing window.

The window is implicitly shown if the "hidden" property is not set.

Windows with the "tooltip" and "menu" properties are popup windows and have the behaviors and guidelines outlined in SDL_CreatePopupWindow().

◆ SDL_GetWindowSurface()

SDL_Surface * SDL_GetWindowSurface ( SDL_Window window)
extern

Get the SDL surface associated with the window.

A new surface will be created with the optimal format for the window, if necessary. This surface will be freed when the window is destroyed. Do not free this surface.

This surface will be invalidated if the window is resized. After resizing a window this function must be called again to return a valid surface.

You may not combine this with 3D or the rendering API on this window.

This function is affected by SDL_HINT_FRAMEBUFFER_ACCELERATION.

◆ SDL_GL_CreateContext()

SDL_GLContext SDL_GL_CreateContext ( SDL_Window window)
extern

Create an OpenGL context for an OpenGL window, and make it current.

Windows users new to OpenGL should note that, for historical reasons, GL functions added after OpenGL version 1.1 are not available by default. Those functions must be loaded at run-time, either with an OpenGL extension-handling library or with SDL_GL_GetProcAddress() and its related functions.

SDL_GLContext is an alias for void *. It's opaque to the application.

Parameters
windowthe window to associate with the context
Returns
the OpenGL context associated with window or NULL on error; call SDL_GetError() for more details.

◆ SDL_GL_ExtensionSupported()

SDL_bool SDL_GL_ExtensionSupported ( const char *  extension)
extern

Check if an OpenGL extension is supported for the current context.

This function operates on the current GL context; you must have created a context and it must be current before calling this function. Do not assume that all contexts you create will have the same set of extensions available, or that recreating an existing context will offer the same extensions again.

While it's probably not a massive overhead, this function is not an O(1) operation. Check the extensions you care about after creating the GL context and save that information somewhere instead of calling the function every time you need to know.

Parameters
extensionthe name of the extension to check
Returns
SDL_TRUE if the extension is supported, SDL_FALSE otherwise.
Since
This function is available since SDL 3.0.0.

◆ SDL_GL_GetProcAddress()

SDL_FunctionPointer SDL_GL_GetProcAddress ( const char *  proc)
extern

Get an OpenGL function by name.

If the GL library is loaded at runtime with SDL_GL_LoadLibrary(), then all GL functions must be retrieved this way. Usually this is used to retrieve function pointers to OpenGL extensions.

There are some quirks to looking up OpenGL functions that require some extra care from the application. If you code carefully, you can handle these quirks without any platform-specific code, though:

  • On Windows, function pointers are specific to the current GL context; this means you need to have created a GL context and made it current before calling SDL_GL_GetProcAddress(). If you recreate your context or create a second context, you should assume that any existing function pointers aren't valid to use with it. This is (currently) a Windows-specific limitation, and in practice lots of drivers don't suffer this limitation, but it is still the way the wgl API is documented to work and you should expect crashes if you don't respect it. Store a copy of the function pointers that comes and goes with context lifespan.
  • On X11, function pointers returned by this function are valid for any context, and can even be looked up before a context is created at all. This means that, for at least some common OpenGL implementations, if you look up a function that doesn't exist, you'll get a non-NULL result that is NOT safe to call. You must always make sure the function is actually available for a given GL context before calling it, by checking for the existence of the appropriate extension with SDL_GL_ExtensionSupported(), or verifying that the version of OpenGL you're using offers the function as core functionality.
  • Some OpenGL drivers, on all platforms, will return NULL if a function isn't supported, but you can't count on this behavior. Check for extensions you use, and if you get a NULL anyway, act as if that extension wasn't available. This is probably a bug in the driver, but you can code defensively for this scenario anyhow.
  • Just because you're on Linux/Unix, don't assume you'll be using X11. Next-gen display servers are waiting to replace it, and may or may not make the same promises about function pointers.
  • OpenGL function pointers must be declared APIENTRY as in the example code. This will ensure the proper calling convention is followed on platforms where this matters (Win32) thereby avoiding stack corruption.
Parameters
procthe name of an OpenGL function
Returns
a pointer to the named OpenGL function. The returned pointer should be cast to the appropriate function signature.

◆ SDL_GL_GetSwapInterval()

int SDL_GL_GetSwapInterval ( int *  interval)
extern

Get the swap interval for the current OpenGL context.

If the system can't determine the swap interval, or there isn't a valid current context, this function will set *interval to 0 as a safe default.

Parameters
intervalOutput interval value. 0 if there is no vertical retrace synchronization, 1 if the buffer swap is synchronized with the vertical retrace, and -1 if late swaps happen immediately instead of waiting for the next retrace
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

See also
SDL_GL_SetSwapInterval

◆ SDL_GL_LoadLibrary()

int SDL_GL_LoadLibrary ( const char *  path)
extern

Dynamically load an OpenGL library.

This should be done after initializing the video driver, but before creating any OpenGL windows. If no OpenGL library is loaded, the default library will be loaded upon creation of the first OpenGL window.

If you do this, you need to retrieve all of the GL functions used in your program from the dynamic library using SDL_GL_GetProcAddress().

Parameters
paththe platform dependent OpenGL library name, or NULL to open the default OpenGL library
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_GL_SetAttribute()

int SDL_GL_SetAttribute ( SDL_GLattr  attr,
int  value 
)
extern

Set an OpenGL window attribute before window creation.

This function sets the OpenGL attribute attr to value. The requested attributes should be set before creating an OpenGL window. You should use SDL_GL_GetAttribute() to check the values after creating the OpenGL context, since the values obtained can differ from the requested ones.

Parameters
attran SDL_GLattr enum value specifying the OpenGL attribute to set
valuethe desired value for the attribute
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_GL_SetSwapInterval()

int SDL_GL_SetSwapInterval ( int  interval)
extern

Set the swap interval for the current OpenGL context.

Some systems allow specifying -1 for the interval, to enable adaptive vsync. Adaptive vsync works the same as vsync, but if you've already missed the vertical retrace for a given frame, it swaps buffers immediately, which might be less jarring for the user during occasional framerate drops. If an application requests adaptive vsync and the system does not support it, this function will fail and return -1. In such a case, you should probably retry the call with 1 for the interval.

Adaptive vsync is implemented for some glX drivers with GLX_EXT_swap_control_tear, and for some Windows drivers with WGL_EXT_swap_control_tear.

Read more on the Khronos wiki: https://www.khronos.org/opengl/wiki/Swap_Interval#Adaptive_Vsync

Parameters
interval0 for immediate updates, 1 for updates synchronized with the vertical retrace, -1 for adaptive vsync
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

int SDL_GL_SwapWindow ( SDL_Window window)
extern

Update a window with OpenGL rendering.

This is used with double-buffered OpenGL contexts, which are the default.

On macOS, make sure you bind 0 to the draw framebuffer before swapping the window, otherwise nothing will happen. If you aren't using glBindFramebuffer(), this is the default and you won't have to do anything extra.

Parameters
windowthe window to change

◆ SDL_MaximizeWindow()

int SDL_MaximizeWindow ( SDL_Window window)
extern

Request that the window be made as large as possible.

Non-resizable windows can't be maximized. The window must have the SDL_WINDOW_RESIZABLE flag set, or this will have no effect.

On some windowing systems this request is asynchronous and the new window state may not have have been applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow() to block until the changes have taken effect.

When the window state changes, an SDL_EVENT_WINDOW_MAXIMIZED event will be emitted. Note that, as this is just a request, the windowing system can deny the state change.

When maximizing a window, whether the constraints set via SDL_SetWindowMaximumSize() are honored depends on the policy of the window manager. Win32 and macOS enforce the constraints when maximizing, while X11 and Wayland window managers may vary.

Parameters
windowthe window to maximize

◆ SDL_RestoreWindow()

int SDL_RestoreWindow ( SDL_Window window)
extern

Request that the size and position of a minimized or maximized window be restored.

On some windowing systems this request is asynchronous and the new window state may not have have been applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow() to block until the changes have taken effect.

When the window state changes, an SDL_EVENT_WINDOW_RESTORED event will be emitted. Note that, as this is just a request, the windowing system can deny the state change.

◆ SDL_SetWindowBordered()

int SDL_SetWindowBordered ( SDL_Window window,
SDL_bool  bordered 
)
extern

Set the border state of a window.

This will add or remove the window's SDL_WINDOW_BORDERLESS flag and add or remove the border from the actual window. This is a no-op if the window's border already matches the requested state.

You can't change the border state of a fullscreen window.

Parameters

◆ SDL_SetWindowFullscreen()

int SDL_SetWindowFullscreen ( SDL_Window window,
SDL_bool  fullscreen 
)
extern

Request that the window's fullscreen state be changed.

By default a window in fullscreen state uses borderless fullscreen desktop mode, but a specific exclusive display mode can be set using SDL_SetWindowFullscreenMode().

On some windowing systems this request is asynchronous and the new fullscreen state may not have have been applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow() to block until the changes have taken effect.

When the window state changes, an SDL_EVENT_WINDOW_ENTER_FULLSCREEN or SDL_EVENT_WINDOW_LEAVE_FULLSCREEN event will be emitted. Note that, as this is just a request, it can be denied by the windowing system.

Parameters
windowthe window to change
fullscreenSDL_TRUE for fullscreen mode, SDL_FALSE for windowed mode
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowFullscreenMode()

int SDL_SetWindowFullscreenMode ( SDL_Window window,
const SDL_DisplayMode mode 
)
extern

Set the display mode to use when a window is visible and fullscreen.

This only affects the display mode used when the window is fullscreen. To change the window size when the window is not fullscreen, use SDL_SetWindowSize().

If the window is currently in the fullscreen state, this request is asynchronous on some windowing systems and the new mode dimensions may not be applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow() to block until the changes have taken effect.

When the new mode takes effect, an SDL_EVENT_WINDOW_RESIZED and/or an SDL_EVENT_WINDOOW_PIXEL_SIZE_CHANGED event will be emitted with the new mode dimensions.

Parameters
windowthe window to affect
modea pointer to the display mode to use, which can be NULL for borderless fullscreen desktop mode, or one of the fullscreen modes returned by SDL_GetFullscreenDisplayModes() to set an exclusive fullscreen mode.
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowGrab()

int SDL_SetWindowGrab ( SDL_Window window,
SDL_bool  grabbed 
)
extern

Set a window's input grab mode.

When input is grabbed, the mouse is confined to the window. This function will also grab the keyboard if SDL_HINT_GRAB_KEYBOARD is set. To grab the keyboard without also grabbing the mouse, use SDL_SetWindowKeyboardGrab().

If the caller enables a grab while another window is currently grabbed, the other window loses its grab in favor of the caller's window.

Parameters
windowthe window for which the input grab mode should be set
grabbedSDL_TRUE to grab input or SDL_FALSE to release input
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowHitTest()

int SDL_SetWindowHitTest ( SDL_Window window,
SDL_HitTest  callback,
void *  callback_data 
)
extern

Provide a callback that decides if a window region has special properties.

Normally windows are dragged and resized by decorations provided by the system window manager (a title bar, borders, etc), but for some apps, it makes sense to drag them from somewhere else inside the window itself; for example, one might have a borderless window that wants to be draggable from any part, or simulate its own title bar, etc.

This function lets the app provide a callback that designates pieces of a given window as special. This callback is run during event processing if we need to tell the OS to treat a region of the window specially; the use of this callback is known as "hit testing."

Mouse input may not be delivered to your application if it is within a special area; the OS will often apply that input to moving the window or resizing the window and not deliver it to the application.

Specifying NULL for a callback disables hit-testing. Hit-testing is disabled by default.

Platforms that don't support this functionality will return -1 unconditionally, even if you're attempting to disable hit-testing.

Your callback may fire at any time, and its firing does not indicate any specific behavior (for example, on Windows, this certainly might fire when the OS is deciding whether to drag your window, but it fires for lots of other reasons, too, some unrelated to anything you probably care about and when the mouse isn't actually at the location it is testing). Since this can fire at any time, you should try to keep your callback efficient, devoid of allocations, etc.

Parameters
windowthe window to set hit-testing on
callbackthe function to call when doing a hit-test
callback_dataan app-defined void pointer passed to callback
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowInputFocus()

int SDL_SetWindowInputFocus ( SDL_Window window)
extern

Explicitly set input focus to the window.

You almost certainly want SDL_RaiseWindow() instead of this function. Use this with caution, as you might give focus to a window that is completely obscured by other windows.

Parameters
windowthe window that should get the input focus
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowKeyboardGrab()

int SDL_SetWindowKeyboardGrab ( SDL_Window window,
SDL_bool  grabbed 
)
extern

Set a window's keyboard grab mode.

Keyboard grab enables capture of system keyboard shortcuts like Alt+Tab or the Meta/Super key. Note that not all system keyboard shortcuts can be captured by applications (one example is Ctrl+Alt+Del on Windows).

This is primarily intended for specialized applications such as VNC clients or VM frontends. Normal games should not use keyboard grab.

When keyboard grab is enabled, SDL will continue to handle Alt+Tab when the window is full-screen to ensure the user is not trapped in your application. If you have a custom keyboard shortcut to exit fullscreen mode, you may suppress this behavior with SDL_HINT_ALLOW_ALT_TAB_WHILE_GRABBED.

If the caller enables a grab while another window is currently grabbed, the other window loses its grab in favor of the caller's window.

Parameters
windowThe window for which the keyboard grab mode should be set.
grabbedThis is SDL_TRUE to grab keyboard, and SDL_FALSE to release.
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowPosition()

int SDL_SetWindowPosition ( SDL_Window window,
int  x,
int  y 
)
extern

Request that the window's position be set.

If, at the time of this request, the window is in a fixed-size state such as maximized, this request may be deferred until the window returns to a resizable state.

This can be used to reposition fullscreen-desktop windows onto a different display, however, exclusive fullscreen windows are locked to a specific display and can only be repositioned programmatically via SDL_SetWindowFullscreenMode().

On some windowing systems this request is asynchronous and the new coordinates may not have have been applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow() to block until the changes have taken effect.

When the window position changes, an SDL_EVENT_WINDOW_MOVED event will be emitted with the window's new coordinates. Note that the new coordinates may not match the exact coordinates requested, as some windowing systems can restrict the position of the window in certain scenarios (e.g. constraining the position so the window is always within desktop bounds). Additionally, as this is just a request, it can be denied by the windowing system.

Parameters
windowthe window to reposition
xthe x coordinate of the window, or SDL_WINDOWPOS_CENTERED or SDL_WINDOWPOS_UNDEFINED

◆ SDL_SetWindowResizable()

int SDL_SetWindowResizable ( SDL_Window window,
SDL_bool  resizable 
)
extern

Set the user-resizable state of a window.

This will add or remove the window's SDL_WINDOW_RESIZABLE flag and allow/disallow user resizing of the window. This is a no-op if the window's resizable state already matches the requested state.

You can't change the resizable state of a fullscreen window.

Parameters
windowthe window of which to change the resizable state
resizableSDL_TRUE to allow resizing, SDL_FALSE to disallow
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowSize()

int SDL_SetWindowSize ( SDL_Window window,
int  w,
int  h 
)
extern

Request that the size of a window's client area be set.

NULL can safely be passed as the w or h parameter if the width or height value is not desired.

If, at the time of this request, the window in a fixed-size state, such as maximized or fullscreen, the request will be deferred until the window exits this state and becomes resizable again.

To change the fullscreen mode of a window, use SDL_SetWindowFullscreenMode()

On some windowing systems, this request is asynchronous and the new window size may not have have been applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow() to block until the changes have taken effect.

When the window size changes, an SDL_EVENT_WINDOW_RESIZED event will be emitted with the new window dimensions. Note that the new dimensions may not match the exact size requested, as some windowing systems can restrict the window size in certain scenarios (e.g. constraining the size of the content area to remain within the usable desktop bounds). Additionally, as this is just a request, it can be denied by the windowing system.

Parameters
windowthe window to change
wthe width of the window, must be > 0
hthe height of the window, must be > 0
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_SetWindowTitle()

int SDL_SetWindowTitle ( SDL_Window window,
const char *  title 
)
extern

Set the title of a window.

This string is expected to be in UTF-8 encoding.

Parameters
windowthe window to change
titlethe desired window title in UTF-8 format
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_ShowWindow()

int SDL_ShowWindow ( SDL_Window window)
extern

Show a window.

Parameters
windowthe window to show
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_ShowWindowSystemMenu()

int SDL_ShowWindowSystemMenu ( SDL_Window window,
int  x,
int  y 
)
extern

Display the system-level window menu.

This default window menu is provided by the system and on some platforms provides functionality for setting or changing privileged state on the window, such as moving it between workspaces or displays, or toggling the always-on-top property.

On platforms or desktops where this is unsupported, this function does nothing.

Parameters
windowthe window for which the menu will be displayed
xthe x coordinate of the menu, relative to the origin (top-left) of the client area
ythe y coordinate of the menu, relative to the origin (top-left) of the client area
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.
Since
This function is available since SDL 3.0.0.

◆ SDL_SyncWindow()

int SDL_SyncWindow ( SDL_Window window)
extern

Block until any pending window state is finalized.

On asynchronous windowing systems, this acts as a synchronization barrier for pending window state. It will attempt to wait until any pending window state has been applied and is guaranteed to return within finite time. Note that for how long it can potentially block depends on the underlying window system, as window state changes may involve somewhat lengthy animations that must complete before the window is in its final requested state.

On windowing systems where changes are immediate, this does nothing.

Parameters
windowthe window for which to wait for the pending state to be applied
Returns
0 on success, a positive value if the operation timed out before the window was in the requested state, or a negative error code on failure; call SDL_GetError() for more information.

This function is available since SDL 3.0.0.

◆ SDL_UpdateWindowSurface()

int SDL_UpdateWindowSurface ( SDL_Window window)
extern

Copy the window surface to the screen.

This is the function you use to reflect any changes to the surface on the screen.

This function is equivalent to the SDL 1.2 API SDL_Flip().

Parameters
windowthe window to update
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.

◆ SDL_UpdateWindowSurfaceRects()

int SDL_UpdateWindowSurfaceRects ( SDL_Window window,
const SDL_Rect rects,
int  numrects 
)
extern

Copy areas of the window surface to the screen.

This is the function you use to reflect changes to portions of the surface on the screen.

This function is equivalent to the SDL 1.2 API SDL_UpdateRects().

Note that this function will update at least the rectangles specified, but this is only intended as an optimization; in practice, this might update more of the screen (or all of the screen!), depending on what method SDL uses to send pixels to the system.

Parameters
windowthe window to update
rectsan array of SDL_Rect structures representing areas of the surface to copy, in pixels
numrectsthe number of rectangles
Returns
0 on success or a negative error code on failure; call SDL_GetError() for more information.
